.SH NAME
std::showpos,std::noshowpos \- std::showpos,std::noshowpos

.SH Synopsis
   Defined in header <ios>
   std::ios_base& showpos( std::ios_base& str );   \fB(1)\fP
   std::ios_base& noshowpos( std::ios_base& str ); \fB(2)\fP

   Enables or disables the display of the plus sign '+' in non-negative integer output.
   Has no effect on input.

   1) Enables the showpos flag in the stream str as if by calling
   str.setf(std::ios_base::showpos).
   2) Disables the showpos flag in the stream str as if by calling
   str.unsetf(std::ios_base::showpos).

   This is an I/O manipulator, it may be called with an expression such as out <<
   std::showpos for any out of type std::basic_ostream or with an expression such as in
   >> std::showpos for any in of type std::basic_istream.

.SH Parameters

   str - reference to I/O stream

.SH Return value

   str (reference to the stream after manipulation).

.SH Example


// Run this code

 #include <iostream>

 int main()
 {
     std::cout
         << "showpos: " << std::showpos << 42 << ' ' << 3.14 << ' ' << 0 << '\\n'
         << "noshowpos: " << std::noshowpos << 42 << ' ' << 3.14 << ' ' << 0 << '\\n';
 }

.SH Output:

 showpos: +42 +3.14 +0
 noshowpos: 42 3.14 0
